DIY Boat Hull Liner Replacement

X-HT-300652

Hull liner is an important, but sometimes overlooked, portion of a sport boat's interior. A liner gives the inside of the hull — the "walls" of the boat — a polished finish. It also protects the hull from stains, scratches and other damage while adding a layer of padding and marine insulation. In this tutorial video, we'll show you how to replace the old hull liner on your boat with high-quality Boat Blanket fabric.

Boat Blanket is a durable marine carpeting material. Its resistance to mold and mildew makes it a top choice for hull liner on boats where the upholstery is exposed to the elements. It’s also solution-dyed and highly UV resistant, so its color will stick around for the long haul no matter what hue you choose. While Boat Blanket is intended to be a protective material, its softness will make it feel more like a luxury feature of your boat’s interior than anything else.
